Original application January 20,1943, Serial No. 472,999. Divided andthis application January 31, 1945, Serial No. 575,411 r This inventionpertains to new and useful lmprovements in hose clamps, and is adivision of my application Serial No. 472,999, filed January 20, 1943,which matured into Patent No. 2,371,439. The primary object of thepresent invention is to provide, in a clamp of the type including ametallic strap, a novel construction and arrangement whereby aconventional coupling may be expeditiously and firmly anchored in a hosewithout the use of screws, bolts, wire, et cetera.

Other objects of the invention are to provide 1 Claim. (c1. zen-s4) 2 4from the inner side of said clip and bent back, as at 9. The strap 8 isthen passed beneath the other clip 4 and inserted beneath the loops 6 ofboth of said clips. The other or free end pora hose clamp of theaforementioned character which will be comparatively simple inconstruction, strong, durable, compact and which may be manufactured atlow cost.

All of the foregoing and still further objects and advantages of theinvention will become apparent from a studyof the followingspecification, taken in connection with the accompanying drawing whereinlike characters of reference designate corresponding parts throughouttheseveral views, and wherein:

Figure 1 is a view in side elevation, showing a clamp constructed inaccordance with the present invention in use.

Figure 2 is a view in end elevation thereof.

Figure 3 is a cross sectional view, taken substantially on the line 3-3of Figure 1.

Figure 4 is a plan view of one of the clips.

Figure 5 is an end elevational view of one of the clips.

Referring now to the drawing in detail, it will be seen that referencecharacter I designates an end portion of a hose. A conventional coupling2 has one end portion engaged in the hose l. The coupling 2 includestheusual flange 3 for abutting engagement with the end of the hose 1.

The embodiment of the present invention which has been illustratedcomprises a plurality of clips 4 in the form of elongated metallicsheets of arcuate cross section which are mounted longitudinally ontheend portion of the hose I. At one end, the clips 4 terminate in inturnedhooks 5 which are engageable with thefiange 3 for anchoring the coupling2 in the hose 1. Struck outwardly from intermediate portions of theclips 4 are longitudinally elongated loops 6 providing slots I in saidclips. The loops 6 and the slots I accommodate a metallic strap 8 whichis wrapped tightly around the hose l for firmly securing the clips 4thereon and for compressing said hose on the coupling 2. l

As illustrated to advantagein Figure 3 of the drawing, one end portionof the metalllcstrap a is inserted through the slot I of one of theclips tion of the metallic strap 8 is then inserted again beneath theloop 6 of said one clip 4 and tightened. In this manner the hose I iscompressed about the nozzle 2. This end portion of the metallic strap 8is then bent back, as at ill, for securing the clamp tightly on the hoseand for compressing said hose on the coupling 2.

It is believed that the many advantages of a hose clamp constructed inaccordance with the present invention will be readily understood, andalthough a preferred embodiment of the device is as illustrated anddescribed, it is to be understood that changes in the details ofconstruction may be resorted to which will fall within the scope of theinvention as claimed.

What is claimed is:

A hose clamp comprising, in combination, a pair of similar separateclips in the form of elongated sheets of arcuate cross section adaptedto be mounted and secured longitudinally of and upon opposite sides of ahose and to partially embrace the latter to secure a flanged fittingtherein, each clip having an inturned hook at one end engageable withthe flange of the fitting and having a longitudinal loop struckoutwardly therefrom intermediate the sides thereof to form a slot in theclip inwardly of the loop, and a separate metallic strap having an endinserted outwardly through the slot of one clip and bent back over thelatter at one side of its slot, said strap being tightly passed aroundone side of the hose and beneath the other clip, then tightly around theother side of the hose and through the loop of said one clip, thentightly around both sides of the hose and through the loops of bothclips, the other end of the strap being bent over the loop of said oneclip to secure the strap in tight condition with the hose compressed onthe fitting.
